LIQUID-FUEL BURNER.

Specification of Letters Patent. Patented J une 3, 1919.

Application filed December 10, 1918. Serial No. 266.049.

'T 0 all whom it may concern which I have provided for that purpose.

My improvements are, however, readily adapted and desirable for use in other firepots as, for instance, heating stoves and furnaces.

The main objects of this invention are: First, to provide an improved fuel burner for burning liquid hydrocarbon fuel, as kerosene, which is of very high efficiency.

Second, to provide an improved liquid burner Which is simple and economical and durable in its parts and readily installed 1n a firepot.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to, follow.

I accomplish the objects of my invention by the defices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail view of a structure embodying the features of my invention, the firepot being shown mainly in conventional form and partially in vertical section as are parts of my improved burner.

Fig. II is a detail plan view of my improved burner.

Fig. III is a transverse section on a line corresponding to line 33 of Figs. I and II.

Fig. IV is a detail end elevation looking from the left of Fig. II.

In the drawing similar reference characters refer to similar parts throughout the several views.

Referring to the drawing, 1 represents the firepot of a cooking stove or range and 2 the grate thereof. As the details of these parts form no part of my present invention they are not further described herein and I have not attempted to show or maintain the relative proportion of the parts.

My improved burner comprises a body member 3 which, in practice, is preferably a pan-like casting adapted as a waterreceptacle. This body member is adapted to rest upon the bottom or grate bars of the firepot. Across the top of the body member is a channeled or trough-like support 4 for the burner. 7

At one end the body member is provided with an upwardly projecting rest 5 having a hole 6 therein for the fuel supply pipe 7. At its opposite end the body member is provided with an upwardly projecting shouldered rest 8. The burner comprises a pair of members 9 and 10 disposed horizontally one above the'o-ther,-the lower member being arranged in thetrough-like support f and the member 10 above it; 1 The member 9 is provided with a jet orifice 11, while the member 10 has a deflector 12 mounted thereon above the jet orificeso that the flames are directed horizontally acrossthe pan and consequently across the water therein. I A y The members 9 and 10 are connected by a coupling 13 at their inner ends, while the outer end of the member 10 is connected by I U-coupling 14 to the fuel pipe 7. This coupling 14 is disposed on the rest 8.

The support 4 is provided with an absorbent 15 so that in starting the burner the fuel may be turned on and allowed to overflow into the trough 15 and when ignited will heat the burner and the supply pipe 7 sufiiciently to generate gas or convert the liquid fuel into a gaseous vapor. The source of supply is indicated at 16 and this is connected to the pipe 7 through the pipe 17 controlled by the valve 18 regulating the flow of fuel. The heat from the burner evaporates the water in the pan, and the vapor mixing with the gasified fuel causes very perfect combustion greatly increasing the heat capacity of the burner and also preventing the deposit of carbon.

The applicant finds that when the pan is properly supplied with water the burner is substantially noiseless; that there is practi- V cally no carbon deposited and that there is water is omitted from the pan. The applicant ascribes this lack of noise to the perfect combustion obtained. The structure, however, has certain advantages as a burner when used without water.

I have illustrated and described my im provements in an adaptation for cooking stoves and ranges. I have not attempted to illustrate or describe adaptations to other forms of stoves and furnaces, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is:

1. In a liquid fuelburner, the combination with a pan-like body member constituting a water receptacle and having a support extending across the top thereof, and upwardly projecting rests on opposed walls, one rest having an opening therein and the other being shouldered, afuel supply pipe disposed through said opening, a burner comprising a pair'of horizontal members disposed one above the other connected at their inner ends, the lower member being disposed on said support and provided with a jet orifice, the outer end of the upper member being connected to said pipe by a horizontally disposed U-coupling engaged with said shouldered rest, and a deflector disposed on the upper burner member above said jet orifice.

2. In a liquid fuel burner, the combination with a body member having a trough-like support extending across the top thereof, and upwardly projecting rests on opposed walls, one rest having an opening therein and the other being shouldered, a fuel supply pipe disposed through said opening, a burner comprising a pair of horizontal members disposed one above the other connected at their inner ends, the lower member being disposed in said support and provided with a jet orifice, the outer end of the upper member being connected to said pipe by a, horizontally disposed U=c0upling engaged with said shouldered rest, and a deflector disposed on the upper burner member above said jet orifice.

3. In a liquid fuel burner, the combination with a body member having a trough-like support extending across the top thereof, and upwardly projecting rests on opposed walls, one rest having an opening therein and the other being shouldered, a fuel supply pipe disposed through said opening, and a burner comprising a pair of horizontal members disposed one above the other connected at their inner ends, the lower member being disposed in said support and provided with a jet orifice, the outer end of the upper member being connected to said pipe by a horizontally disposed U-eoupling engaged with said shouldered rest.

a. In a liquid fuel burner, the combination with a pan-like body member constituting a water receptacle and having a trough-like support extending across the top thereof, a fuel supply pipe, a burner comprising a pair of horizontal members disposed one above the other connected at their inner ends, the lower member being disposed in said support and provided with a jet orifice, the outer end of the upper member being connected to said pipe, and a deflector disposed on the upper burner member above said jet orifice.

5. In a liquid fuel burner, the combination of a body member constituting a water receptacle having a channeled support at the top thereof, a fuel supply pipe, a burner comprising a pair of horizontal members disposed one above the other connected at one end, said pipe being connected to the other end of the upper member, the lower member being disposed in said trough and provided with a jet orifice, and a deflector disposed on the upper burner member above said jet orifice.

6. In a liquid fuel burner, the combination of a body member constituting a water receptacle having a channeled support at the top thereof, a fuel supply pipe, and a burner comprising a. pair of horizontal members disposed one above the other connected at one end, said pipe being connected to the other end of the upper member, the lower member being disposed in said trough and provided with a jet orifice.

T. In a liquid fuel burner, the combination of a body member having a channeled support at the top thereof, a fuel supply pipe, and a burner comprising a. pair of horizontal members disposed one above the other connected at one end, said pipe being connected to the other end of the upper member, the lower member being disposed in said trough and provided with a jet orifice, said trough being provided with an absorbent.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
